Description

  The present invention relates to a seismic structure and a method for forming the seismic structure, and more particularly to a seismic structure having a load-bearing damping member in a structural frame of a building composed of vertical members and cross members.

  Conventionally, building of earthquake-resistant structure has been promoted against the backdrop of a huge earthquake disaster. Especially in wooden buildings, bearing walls using earthquake-resistant members for the purpose of damage prevention and damping walls using damping members are known.

  The bearing wall is a structure in which a brace is inserted between the corners of two longitudinal members constituting the structural frame, or a structural plywood is nailed to the entire structural frame. By adopting a structure in which a brace is put in the structure frame or a structure in which a structural plywood is nailed to the entire structure frame, the structure frame can be prevented from being deformed, and horizontal force due to seismic force or wind pressure can be prevented. A structure that can resist directional force is called an earthquake resistant structure.

  On the other hand, the damping wall is a structure in which, for example, an auxiliary member formed of a steel pipe member or the like is attached to a damping device attached to a structural frame, and a horizontal force is transmitted to the damping device via the auxiliary member. Since the horizontal force is transmitted to the vibration control device through the auxiliary member attached to the structural frame in this way, when the horizontal force due to an earthquake or wind acts on the building, the vibration control device attenuates this force. A structure that reduces the displacement of the building is called a vibration control structure (see, for example, Patent Document 1).

  As mentioned above, the bearing wall is a structure that strengthens the building so that it can withstand earthquakes, and the damping wall is a structure that tries to reduce the shaking of the earthquake transmitted to the building. Damping walls have different structures and effects.

  In the seismic structure with these bearing walls and damping walls, since there are seismic members inside the walls, it is difficult to install openings such as windows. It is necessary to arrange so that can be secured.

  However, damping walls, which are often used as a means to control or control the deformation behavior of a building, are treated as auxiliary means under the current Building Standards Law, so they are resistant to horizontal forces such as earthquakes. In order to ensure earthquake resistance, legally effective bearing walls are mainly used. Damping walls are used only as auxiliary means for deformation damping. The bearing wall and the seismic wall must be used together as they work separately. When the bearing wall and the vibration control wall are used together in this way, the wall surface on which the opening can be installed decreases, and the ratio of the closed wall surface inevitably increases. Thus, when the ratio of the closed wall surface is increased, the degree of freedom in design is remarkably lowered, and the convenience of living is impaired in terms of design planning.

  In order to obtain the necessary and sufficient seismic performance even if the location of the bearing walls and damping walls is reduced as a countermeasure against these, a method of placing the bearing walls and damping walls in the same position in a plane can be considered. . However, as long as no legal evaluation of the damping wall is given, the required amount of wall is not halved in terms of structural calculations due to interference and resonance between the two. In addition, since the earthquake-resistant member and the vibration-damping member are used so as to overlap the wall at the same position, the wall becomes thick, resulting in a problem that the living space becomes narrow.

  The present invention has been made in view of these points, and relates to a new earthquake-resistant structure in which a damping function is added to a bearing wall and a method for forming the same. With the same wall thickness as the conventional load-bearing wall in the seismic structure of the wooden building wall, it is possible to legally ensure freedom of design planning, load-bearing seismic structure that combines load-bearing performance and vibration control performance, and An object is to provide a method for forming the same.

  In the present invention, in order to solve the above-described problem, in a load-bearing earthquake-resistant structure having a vibration control member in a structural frame of a building composed of vertical members and cross members, fixings provided on opposing surfaces in the structural frame member There is provided a load-bearing earthquake-resistant structure comprising a portion and a filling material connected to the structural frame via the fixing portion, wherein at least one of the fixing portions is a vibration control device.

  As a result, when a force that deforms the structural frame is applied by an earthquake, the satiety material provided in the structural frame via the fixed portion resists the stress caused by the earthquake, and the vibration control provided in at least one of the fixed portions. The device attenuates the stress caused by the earthquake.

  Further, in the present invention, in a load-proof and earthquake-resistant structure having a vibration control member in a structural frame of a building composed of vertical members and cross members, a step of providing a fixing portion in the structural frame, and at least of the fixing portion There is provided a method for forming a load-bearing and earthquake-resistant structure, comprising a step of providing a vibration control device in one and a step of connecting the satiety material to the structural frame via the fixing portion.

  As a result, when stress due to an earthquake applied to the load-bearing seismic structure is transmitted to the structural frame, the filling material provided to the structural frame via the fixing portion counters the stress due to the earthquake and is provided in at least one of the fixing portions. The damping device that damps the stress caused by the earthquake.

According to the load-bearing earthquake-resistant structure of the present invention, when stress due to an earthquake applied to the load-bearing earthquake-resistant structure is transmitted to the structural frame, the filling material provided to the structural frame via the fixed portion counteracts the stress caused by the earthquake, and the fixed portion Because the vibration control device provided in at least one of the above slides in the vertical direction to attenuate the stress caused by the earthquake, the vibration control wall is treated as an auxiliary means in the current Building Standards Law. It has been confirmed to give rigidity and yield strength.
Moreover, since the damping wall and the bearing wall can be unified, the ratio of the closed wall surface is reduced, and the opening can be increased by that amount. This can improve design freedom, life rationality and convenience.

[First Embodiment]
FIG. 1 is a front view showing an earthquake-resistant structure according to the first embodiment.
As shown in FIG. 1, the earthquake-resistant member 100 includes a vibration control device 110, a fixing bracket 120, and two front and back satiety members 130. For the sake of convenience, the satiety material 130 indicated by the oblique lines on the front side in the structural frame 200 in FIG. 1 is referred to as the first satiety material 130, and the back satiety material 130 in the other structural frame 200 is defined as the second satisfiable material 130. And

  Further, the structural frame 200 of the wooden building is formed by fixing two left and right vertical members 210 and two upper and lower horizontal members 220 connecting the two. The interval between the vertical members 120 can be set to be wide or narrow depending on the structural plan of the building.

The installation method of the earthquake-resistant member 100 is installed in the following procedures, for example.
The vibration control device 110 is fixed to a longitudinal three-part dividing point of the two vertical members 210 with a plurality of screws (not shown), for example, square bit screws, toward the center direction of the structural frame 200.

  Next, a screw (not shown), for example, a square bit screw, is placed at the center of the two vertical members 210 and slightly toward the center of both ends of the two vertical members 210 so that the fixing bracket 120 faces the vibration control device 110. Secure with.

  Next, the first satiety member 130 processed into a shape along the inside of the structural frame 200 is built from the front side of the structural frame 200 in FIG. 1 so that the first satiety member 130 does not interfere with the structural frame 200. The first satiety member 130 is fixed to two seismic control devices 110 fixed to one longitudinal member 210 and three fixing brackets 120 fixed to the other longitudinal member 210 with screws (not shown) such as coarse thread screws. To do. Thereby, the first satiety member 130 is connected to the structural frame 200 via the vibration control device 110 and the fixing bracket 120. In addition, it is necessary to cut out the portions where the front and back satiety members 130 interfere with the vibration control device 110 and the fixing bracket 120 in advance, but the shape to be cut will be described later.

  Next, the second satiety material 130 processed into a shape along the inside of the structural frame 200 is erected from the back side of the structural frame 200 in FIG. 1 so that the second satisfiable material 130 does not interfere with the structural frame 200. The second satiety material 130 is fixed to the two seismic control devices 110 and the three fixing brackets 120 that are not fixed to the first satiety material 130 with screws (not shown) such as coarse thread screws. Thereby, the second satiety member 130 is connected to the structural frame 200 via the vibration control device 110 and the fixing bracket 120. Therefore, the earthquake-resistant member 100 is connected to the structural frame 200 via the vibration control device 110 and the fixing bracket 120.

  The two front and back satiety members 130 may interfere with the structural frame 200, the vibration control device 110, and the fixing bracket 120 due to distortion of the structural frame 200 that receives stress due to the earthquake. It is necessary to cut out the part to be cut in advance. The notched portion will be described later.

  The two front and back filling members 130 are plate-like bodies having strength, such as structural plywood, and are fixed to the structural frame 200 via the fixing bracket 120 and the vibration control device 110 to resist stress caused by earthquakes. I can do it. Further, when the proof strength is particularly required depending on the interval between the vertical members 120 and the number of the vibration control devices, the resistance to resist stress caused by the earthquake can be increased by increasing the thickness of the satiety material 130.

  Moreover, about the shape dimension of the single filling material 130, it is desirable to process and use the structural plywood of thickness 12mm-24mm which is the standard size of the structural plywood.

  Further, when the vibration control device 110 and the fixing bracket 120 are fixed to the vertical member 210, the two front and back satiety members 130 to be fixed later are on the extension of the center line in the height direction of the vertical member 210. It is desirable to adjust and fix.

  In the first embodiment, the satiety material 130 sandwiches the satiety device 110 attached to the structural frame 200 and the satiety material mounting plates 115 and 122 of the fixing bracket 120 as shown in FIGS. 3 and 4. Each is fixed from the front and back.

FIG. 2 is a diagram illustrating a state in which a horizontal force due to an earthquake is applied to the structural frame of the first embodiment.
When a horizontal force P due to an earthquake is applied to the structural frame 200, the stress due to the horizontal force P is transmitted to the two vertical members 210, and two sheets are attached to the front and back through the vibration control device 110 and the fixing bracket 120 fixed to the vertical member 210. The stress is transmitted to the filling material 130. Since the two front and back satin members 130 are fixed to the structural frame 200 so as to sandwich the vibration control device 110 and the fixing bracket 120, the stress due to the horizontal force P in the opposite direction is positive and negative alternating applied to the satin member 130. The compression side of each of the two front and back satin members 130 is compressed in the compression direction, the tension side is uniformly in the tension direction, and the front and back sides of the satiety member 130 are spread evenly. The structure frame 200 is supported by the entire filling material 130 while being inclined and resists the horizontal force P of positive and negative alternating.

  Further, the vertical component force due to the horizontal force P transmitted to the satiety material 130 is a vector generated in the process of tilting the satiety material 130. The vertical component force transmitted to the satiety member 130 is transmitted to the vibration control device 110 connected to the two front and back satiety members 130, and the vertical vibration component 110 slides in the vertical direction. Damping force. Further, since stress due to the horizontal force P is dispersed by the filling material 130, excessive stress is concentrated and is difficult to be transmitted to the vibration control device 110, and the positive and negative alternating horizontal force P applied to the structural frame 200 is applied to the vibration control device 110. Can be efficiently absorbed and attenuated. When the interval between the vertical members 120 of the structural frame 200 is narrow W, the vertical component force Pv derived from the seismic horizontal force P is expressed by Pv = P / W, and when W> 1 m, the vertical component force Pv> P Therefore, the quantity of the vibration control device 110 can be increased and dealt with.

FIG. 3 is a front view showing details of the vibration control device.
As shown in FIG. 3, the vibration control device 110 has an Ω shape. The vibration control device 110 includes a vibration control element 111 made of a steel plate having a low yield point, a base plate made of ordinary steel for mounting on a vertical member, and a filling material mounting plate 115 for mounting a filling material 130. Prepare.

  The damping element 111 is composed of a low yield point steel strip steel plate that plastically deforms when the applied force exceeds the elastic limit, and a base plate 112 made of ordinary steel that is attached to the longitudinal member 210 and two attachment surfaces that are attached to the base plate 112. 113, the two uprights 114 rising from the inner end of the mounting surface 113, and the two uprights 114 are connected, and stress due to the horizontal force P transmitted from the structural frame 200 is applied to the filling material 130 and the filling material. And an upper side surface 116 received via the mounting plate 115.

  Both ends of the upper side surface 116 protrude to the outside of the upright portion 114 and have a shape bent in an Ω shape toward the mounting surface 113.

  The two extension line-shaped attachment surfaces 113 of the vibration control element 111 are welded to the base plate 112, the filling material attachment plate 115 is made of a general steel material, and the longitudinal direction of the extension line-like upper side surface 116 of the vibration control element 111 is made. The base plate 112 is welded so that the cross section in the short direction of the base plate 112 is T-shaped on the center line.

  A plurality of screw holes 117 for fixing the satiety material 130 with screws are formed in the satiety material attaching plate 115, and when fixing the satiety material 130, screws are inserted from the satiety material attaching plate 115 side. Fastening and filling material mounting plate 115 and filling material 130 are fixed. If it tries to fix with the screw from the filling material 130 side, the location of the screw hole 117 opened in the filling material attachment plate 115 is unclear, and the filling material attachment plate 115, the filling material 130, This is to prevent positional displacement when fixing the.

FIG. 4 is a perspective view showing details of the fixing metal fitting according to the first embodiment.
As shown in FIG. 4, in the first embodiment, the fixing bracket 120 includes a base plate 121 for attaching to the longitudinal member 210 and a filling material attachment plate 122 for fixing the filling member 130. The satiety material mounting plate 122 is welded so that the cross section in the short direction of the base plate 121 is perpendicular to the longitudinal center line of the base plate 121 and has a T shape.

  A plurality of screw holes 123 for fixing the satiety material 130 with screws are formed in the satiety material mounting plate 122. When fixing the satiety material 130, screws are inserted from the side of the satiety material mounting plate 122. Fastening, the satiety material mounting plate 122 and the satiety material 130 are fixed. If it tries to fix with the screw from the filling material 130 side, the location of the screw hole 123 opened in the filling material attachment plate 122 is unclear, and the filling material attachment plate 122, the filling material 130, This is to prevent positional displacement when fixing the.

FIG. 5 is a front view showing the shape of the satiety material according to the first embodiment.
As shown in FIG. 5, the shape of the notched satiety material 130 is generally a hull side surface shape. The two front and back filling plates 130 have the same shape and are inversely symmetric.

  The notch 131 needs to be cut out in advance so that the fixing bracket 120 that connects the filling member 130 and the longitudinal member 210 that are attached to the filling member attachment plate so as to overlap each other does not interfere with each other.

  Moreover, since the vibration control device 110 which connects the filling material 130 and the longitudinal member 210 to be overlapped with each other interferes with the cutout portion 132, it is necessary to cut out the cutout portion 132 in advance.

  Although the shape of the notch portion is not particularly specified, if the notch area is increased, the satiety material 130 may be deformed by stress. Therefore, it is desirable to take the notch portion as necessary and sufficient.

  FIG. 6 is a diagram illustrating a state in which a horizontal force is applied to the vibration control device connected to the longitudinal member and the satiety member.

(A) is a figure which shows the state before a horizontal force is added.
As shown in (a), when a horizontal force is not applied, the fixed state is maintained.

(B) is a figure which shows a mode when the horizontal force Pa is added to the direction of the arrow.
As shown in (b), when the horizontal force Pa is applied from the direction of the arrow, if the elastic limit is exceeded by the stress from the horizontal force Pa transmitted to the vibration control device 110 via the filling material 130, the vibration control element 111 is plastic. As shown in FIG. 5B, the upper rising portion 114 is bent outward from the vibration control element 111 and the lower rising portion 114 is bent inside the vibration control element 111.

(C) is a figure which shows a mode that the horizontal force Pb was added to the direction of the arrow.
When the horizontal force Pb in the reverse direction is applied due to the reaction caused by the application of the horizontal force Pa as in (b), the elastic limit is caused by the stress from the horizontal force Pb transmitted to the vibration control device 110 via the filling material 130. If the upper limit is exceeded, the damping element 111 is plastically deformed, and the upper rising part 114 is bent inside the damping element 111 and the lower rising part 114 is bent outside the damping element 111 as shown in FIG. .

  As described above, the horizontal forces Pa and Pb can be attenuated by the vibration control device 110 sliding in the vertical direction by plastic deformation of the vibration control element 111.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. The seismic structure of the present embodiment is substantially the same as the configuration shown in the first embodiment except that the number of satiety materials is one. For this reason, about the component similar to the said 1st Embodiment, the same code | symbol is attached | subjected etc., and the description is abbreviate | omitted suitably.

FIG. 7 is a front view showing the seismic structure according to the second embodiment.
As shown in FIG. 7, the earthquake-resistant member 100 includes a vibration control device 110, a fixing bracket 120, and a filling material 130. Unlike the fixing bracket 120 of the first embodiment, the fixing bracket 120 has one bolt hole for attaching the filling member 130.

  The structural frame 200 of the wooden building is formed of two vertical members 210 on the left and right sides, and two horizontal members 220 on the upper and lower sides connecting the two.

The installation method of the earthquake-resistant member 100 is installed in the following procedures, for example.
The vibration control device 110 is fixed to a longitudinal three-part dividing point of the two vertical members 210 with a plurality of screws (not shown), for example, square bit screws, toward the center direction of the structural frame 200.

  Next, the fixing bracket 120 is fixed to the center of the two cross members 210 with a bolt and a nut (not shown) toward the center of the structural frame 200.

  Next, the satiety material 130 processed into a shape along the inside of the structural frame 200 is built from one side of the structural frame 200 so that the satiety material 130 does not interfere with the structural frame 200. It fixes to the four seismic control devices 110, and it fixes to the two fixing bracket 120 with the volt | bolt and nut which are not shown in figure. Thereby, the filling material 130 is connected with the structural frame 200 via the vibration control device 110 and the fixing bracket 120 (b). The shape of the satiety material 130 will be described later.

  The satiety material 130 is a plate-like body having strength, such as a structural plywood, and can be fixed to the structural frame 200 to resist a horizontal force caused by an earthquake. Further, by increasing the thickness of the filling material 130, it is possible to increase the resistance force that resists the horizontal force.

  Moreover, about the shape dimension of the filling material 130, it is desirable to process and use the plywood of thickness 12mm-24mm which is a standard size.

  Further, when the damping device 110 and the fixing bracket 120 (b) are fixed to the vertical member 210 and the horizontal member 220, the satiety member 130 to be fixed later is adjusted to be on the center line in the height direction of the structural frame 200. It is desirable to fix it.

  In the second embodiment, the satiety material 130 is built from one side of the structural frame 200 and fixed to the structural frame 200 via the vibration control device 110 and the fixing bracket 120. The satiety material 130 may be sandwiched between the seismic control device 110 and the fixing bracket 120 from the front and back of the structural frame 200 such that the upper portion of the satiety material is from the front surface and the lower portion is from the back surface.

FIG. 8 is a diagram illustrating a state in which a horizontal force is applied to the structure frame of the second embodiment.
The horizontal force P due to the earthquake applied to the structural frame 200 is transmitted to the filling material 130 fixed to the structural frame 200 via the vibration control device 110 and the fixing bracket 120. Since the satiety material 130 is fixed to the structural frame 200 by the vibration control device 110 and the fixing bracket 120 and is integrated, the structural frame 200 is deformed by the stress due to the horizontal force P applied to the satiety material 130. Further, the horizontal force P spreads uniformly on the entire surface of the satiety material 130 and supports the structural frame 200 by the entire satiety material 130 to resist the horizontal force P.

  On the other hand, the vertical component force due to the horizontal force P transmitted to the satiety material 130 is transmitted to the seismic control device 110 connected to the satiety material 130, and the seismic control device 110 slides in the vertical direction to generate the vertical component force. Attenuate. In addition, since the stress due to the horizontal force P is dispersed on the surface of the satiety material 130 by the satiety material 130, the horizontal force P applied to the structural frame 200 is suppressed without transmitting excessive stress to the vibration control device 110. The seismic device 110 can be attenuated efficiently. Since the deformation due to the horizontal force P is an alternating horizontal load, only the deformation direction changes between the compression direction and the tension direction, and the deformation amount is non-linear and asymmetric.

FIG. 9 is a perspective view showing details of the fixing metal fitting according to the second embodiment.
As shown in FIG. 9, in the second embodiment, the fixing bracket 120 includes a base plate 121 for attaching to the vertical member 210 and a filling material attachment plate 122 for fixing the filling material 130. The satiety material mounting plate 122 is welded so that the cross section in the short direction of the base plate 121 is perpendicular to the longitudinal center line of the base plate 121 and has a T shape.

  The filling material mounting plate 122 has one bolt hole 124 for fixing the filling material 130 with a bolt. When fixing the satiety material 130, a hole is made in a desired position of the satiety material 130 in accordance with the attachment position, and the satiety material 130 and the satiety material mounting plate 122 are pin-joined with bolts and nuts (not shown). .

FIG. 10 is a front view showing the shape of the satiety material according to the second embodiment.
As shown in FIG. 10, the satiety material 130 has a shape in which four corners of a rectangle are cut off.

  When the structural frame 200 is deformed by the horizontal force P, the notch 133 may need to be cut out in advance because the corners of the filling material 130 and the structural frame 200 may interfere with each other.

  The shape of the notch 133 is not particularly specified, but if the notch area is increased, the satiety material 130 may be deformed by stress, so it is desirable that the notch is necessary and sufficient.

  As described above, by using the earthquake-resistant structure by the load-bearing damping wall and the method thereof according to the present invention, the satiety member 130 fixed to the vertical member 210 via the fixing bracket and the damping device is applied to the horizontal force due to the earthquake. The seismic control device 110 that resists P and is fixed to the longitudinal member 210 and connected to the filling member 130 absorbs and attenuates the horizontal force P caused by the earthquake. As a result, it is possible to easily and inexpensively form an earthquake-resistant structure having both load-bearing performance and vibration control performance, and to ensure freedom of design planning with earthquake resistance that meets the Building Standards Act.

  Moreover, in the said Example, although the four damping devices 110 and the two fixing brackets 120 were used with respect to one filling material 130 like FIG. 7, FIG. 8, these are the conditions of an installation location. The quantity and installation locations of the vibration control device 110 and the fixing bracket 120 can be changed as appropriate.

Also, in the case of narrow walls, the bearing wall using the brace is that the diagonal brace approaches an obtuse angle, and the seismic performance is extremely reduced due to the input loss of horizontal force. It is often handled as a random wall with irregular dimensions that cannot be recognized. On the other hand, it becomes possible to form a narrow earthquake-resistant structure having both the load-bearing performance and the damping performance by using the load-bearing damping member as described above.

  Moreover, the structural frame 200 is structurally integrated by fixing the filling material 130 to the structural frame 200 via the vibration control device 110 and the fixing bracket 120, and the effective cross-sectional area, the sectional modulus, which is the sectional performance of the part, In addition, the second moment of the cross section can be improved.

  Moreover, in the bearing wall using the brace, when the brace angle is increased by the ratio of the height and the interval of the vertical members 210 of the structural frame 200 due to the narrow width, the horizontal force input loss to the structural frame 200 is reduced. Although generated, by using the satiety material 130 that is a planar body, the vertical component force can be evenly supplied to the vibration control device 110, and the earthquake resistance is improved.

  In addition, by using structural plywood for the filling material 130, for example, it becomes easy to adjust and cut the plywood according to the eave height of the building at the construction site, greatly reducing the construction period and cost. Can be reduced.
